TomTom Go 910 Power supply overvoltage problem

The attached might help anyone who has overvoltaged their 910.

Ah, yes, the old "Sense wire" problem! This was a real issue on chargers for the original Go and Gox00 models. It even fried one of my units when I borrowed a charger from a work colleague.
TBH I thought it had been sorted out by the time the Gox10 models came out, but from your experience it looks like it was still lingering.

Later car chargers were better designs.

Since the units and chargers themselves have otherwise adequate internal regulation, I never understood why TomTom scrap the remote sense wire in conjunction with the use of a higher gauge wire in the adapter cable to relieve some of the voltage drop.
